简要总结
The Artificial Pancreas lab at McGill University has developed an optimization algorithm for adults with Type 1 Diabetes (T1D) on Multiple Daily Injection (MDI) therapy with the adjunctive use of glucose sensor technology, collectively known as sensor-augmented MDI therapy. The algorithm is designed to estimate optimal basal-bolus parameters based on the patient's glucose, insulin and meal data over several days. The investigators hope that this algorithm will be better able to improve long-term glycemic targets by reducing HbA1c levels compared to sensor-augmented MDI therapy alone.
详细描述
The changes in eligibility criteria indicated below are from a previously approved amendment but were inadvertently omitted in the previous PRS update made in November of 2020. Therefore, this note serves to clarify the order of updates.
Inclusion: HbA1c ≥ 7.5% in the last 2 months (modification)
Exclusion:
- More than 1 slow-acting injection and unwilling to switch to once a day for the study (addition)
- Severe hypoglycemic episode within one month of admission (addition)
In the subsequent amendment, we modified the timeframe for the HbA1c inclusion criterion to obtain a more accurate representation of their current glucose control at the time of enrollment.

入选标准
- •Males and females ≥ 18 years of age
- •Clinical diagnosis of type 1 diabetes for at least 12 months. The diagnosis of type 1 diabetes is based on the investigator's judgment; C peptide level and antibody determinations are not needed.
- •Undergoing multiple daily injection therapy.
- •Baseline HbA1c value ≥ 7.5% (up to 7 days before or after screening).
排除标准
- •Serious medical illness likely to interfere with study participation or with the ability to complete the trial by the judgment of the investigator.
- •Failure to comply with the study protocol or with the team's recommendations.
- •Injection of isophane insulin (NPH) or any intermediate-acting insulin
- •More than 1 slow-acting injection and unwilling to switch to once a day for the study
- •Current or ≤ 1-month use of other antihyperglycemic agents (Sodium-Glucose Cotransporter 2 inhibitor (SGLT2), Glucagon-Like Peptide-1 (GLP-1), Metformin, Acarbose, etc....).
- •Severe hypoglycemic episode within one month of admission.
- •Severe diabetic ketoacidosis episode within one month of admission
- •Clinically significant nephropathy, neuropathy or retinopathy as judged by the investigator
- •Recent (<6 months) acute macrovascular event e.g. acute coronary syndrome or cardiac surgery
- •Other serious medical illness likely to interfere with study participation or with the ability to complete the trial by the judgment of the investigator.
